Solana Error: Block/string Serialization Problems in the Anchor
Solana, it is essential to understand and handle the errors in the interaction. One of the general problems is the array/string series in the anchoring programs, especially when working with “ordering” objects.
** What causes the error?
When the Solana’s “Order” object interacts, there are two primary problems: the series of arrays and strings as a bytes. If the “token_ids” field contains a row of string, it can lead to order errors if it is not properly treated.
token identifiers as strings
The “token_ids” field is usually defined in the “order” structure as a byte array (for example, [U8; 32]). However, when working with strings, this type of data require further processing. Inchor, when unfortunately this process can lead to problems.
Error occurring
The error occurs when the "order" structures are classified and then longing for again. Here's what happens:

Tested Case: Token ID setting u32
We test the problem usingtoken_idusing a U32 value:
C
Use Anchor_lang :: Prelude ::*-ot;
Use Solana_SDK :: token :: token;
#[Program]
PUB FN Create_order (
PUB INIT_AMOUNT: U64,
PUB token_ids: VEC
) -> result <()> {{
Have an order = order {
Amount: Init_amount,
// token_ids is not actually stored as a string ...
Token_id: token_ids,
};
// Sorison of bytes
Be serialized_order = serde_json :: to_vec (& order)?;
// Deserialize again, calculating a series of strings
Let deserialized_token_ids = serde_json :: from_str (& serialized_order) .unwrap ();
OK (())
}
The above code fails with an error indicating that the token_id field is not actually stored as a string.

Conclusion
In Solana, series errors, especially when array/string series, can lead to unexpected behavior if they interact with the “order” objects. Solica blockchain.
